Excessive production of reactive oxygen species associated with deficient antioxidant defenses in preterm infants have been implicated in neonatal diseases such as periventricular leukomalacia, intraventricular hemorrhage, bronchopulmonary dysplasia, retinopathy of prematurity, and necrotizing enterocolitis The effect of free radicals in the pathogenesis of preterm neonatal diseases are discussed in this review.

Abstract

AbstractFree radicals (FRs) are unstable, short lived, and highly reactive molecules thatare continuously generated by endogenous and exogenous mechanisms Small amounts of free radicals are generated continuously in living organisms and are necessary for normal cell reactions and cell growth. In neonatal period, hypoxia, ische-mia, ischemia reperfusion, hyperoxia, inflammation, mitochondrial impairment, presence of nonprotein bound iron are responsible of excessive FRs production. The dangerous effects of FRs are linked to their property of being very unstable moleculesand their ability to react with polyunsaturated fatty acids of cell membranes, proteins, polysaccharides, nucleic acids, causing functional alterations within the cell. Excessive production of reactive oxygen species associated with deficient antioxidant defenses in preterm infants have been implicated in neonatal diseases such as periventricular leukomalacia, intraventricular hemorrhage, bronchopulmonary dysplasia, retinopathy of prematurity, and necrotizing enterocolitis The effect of free radicals in the pathogenesis of preterm neonatal diseases are discussed in this review.

Özet

ÖzSerbest radikaller (FR), sürekli olarak endojen ve eksojen mekanizmalarla üretilen, kararsız, kısa ömürlü ve oldukça reaktif moleküllerdir. Canlı organizmalardaaz miktarda serbest radikal üretilir ve normal hücre reaksiyonları ve hücre büyümesi için gereklidir. Yenidoğan döneminde hipoksi, iskemi, iskemi reperfüzyonu, hiperoksi, inflamasyon, mitokondriyal yetmezlik, proteine bağlı olmayan demir aşırı FR üretiminden sorumludur. FR'lerin tehlikeli etkileri, çok kararsız molekül olmaözelliklerine ve hücre membranları, proteinler, polisakaritler, nükleik asitlerden oluşan çoklu doymamış yağ asitleri ile reaksiyona girebilme yetenekleri ile bağlantılıdır ve bu da hücre içinde işlevsel değişikliklere neden olur. Preterm bebeklerde antioksidan savunmanın yetersizliği ve reaktif oksijen türlerinin aşırı miktarda üretimi, periventriküler lökomalazi, intraventriküler kanama, bronkopulmoner displazi,prematüre retinopatisi ve nekrotizan enterokolit gibi yenidoğan hastalıklarının oluşumunda rol oynar. Bu yazıda pretermlerdeki neonatal hastalıkların patogenezinde serbest radikallerin etkisi tartışılmıştır.
